CATER Final Workshop
CATER way forward: Recommendations
Dr Romain Kervarc
19 September 2017, Madrid, Spain

2. Recommendations and report
An entry point for stakeholders and policy makers
CATER work allows:
Identifying gaps
gathering stakeholder feedback
and from this, producing recommendations
Stakeholders and policy makers have different areas of interest and different priorities and do not seek the same information

3. Limiting factors Infrastructures: Organisation: Technology: Airports
Ground transportation …
Organisation:
Passenger flow
Travel information
Technology:
Security check
Faster planes

4. Areas of interest for all actors
Cost (economic/social/R&I) impact:
Airline point of view: if you want to lower delays due to aircraft maintenance, you must schedule your maintenance operations differently and/or increase your fleet or reduce your coverage to be sure to have a plane available
Airport point of view: whether you make security control, boarding, connection more efficient, you will have more constraints and their management will have a cost (more staff, more adaptative organisation, …)
Policy maker point of view: if you set objectives, local executive bodies may have to make investments (multimodal transportation, new airports…): may they face them reallistically? and are they supported by the population?
Safety/Security/Environmental impact:
Airline point of view: do tighter schedules have an impact on safety?
Airport point of view: how to have quicker controls with same security?
Policy maker point of view: more flights mean more carbon…

5. Report Analysis is related to ACARE goals
Analysis may show impact on several stages of the door-to-door model:
From Door to Origin Airport
At Origin Airport
From Gate to Gate
At Transit Airport
At Destination Airport
From Destination Airport to Door
Analysis involves four identified factors of efficiency:
Speed
Frequency
Reliability
Connectivity

6. Recommendation
Elaboration

7. Recommendation elaboration: overview
Recommendation elaboration process
Gap analysis
Stakeholder consultation
BARRIER:
Lack of direct flights
STAKEHOLDER FEEDBACK …
Infrastructure: . infrastructure is the time limiting factor experts unanimously support develop- ment of inter-modality, connecting small airports other transports
IMPACT IDENTIFICATION
System: switch from a hub model to a distributed model – modelling abilities
Costs: financial sustainability and environmental cost of the change
Infrastructure: impact of additional traffic and comparison to intermodal solutions
CLASSIFICATION:
ACARE goal #1
D2D segment #3 Efficiency factor #4
INTEREST AREAS
Do we have the possibility to assess the impact of more direct flights on existing infrastructure capacities?
Are we able to compare the benefits of more direct flights with the benefits of approaches including more intermodality?
RECOMMENDATION BASIS
Impact on existing infrastructure capacities? not much addressed (general focus on hubs), effect on hub congestion not addressed
More direct flights vs more intermodality? Projects addressing intermodality based on existing means, no simulation framework, however adaptation to disruption addressed

8. Recommendation elaboration
Barrier identified in Gap analysis
Barrier 1: Lack of direct flights between a given airport and the 25 busiest airports in Europe
Addressed goal: 90% of travellers within Europe able to complete their journey door-to-door within 4 hours
D2D model segment: 3 – From Gate to Gate
Efficiency factor: 4 – Connectivity

9. Classification of impacts:
Technology: no direct impact
System: one would switch from a hub model to a more distributed model
ability of ATM to handle the change (less flights between hubs, more direct flights)?
other benefits to be expected: less congestion in major hubs?
consequences of creation of new routes (compliance with regulations)?
Costs: consequences of the change of model
sustainability of the model for airlines? consequences on ticket fares?
consequences on airport operation costs?
environmental cost: actual assessment of fuel per capita needed in both cases?
Infrastructure: impact of additional traffic and comparison to intermodal solutions
existing structures sufficient or need for extension?
environmental impact (chemical pollution / noise pollution)?
benefits compared to increase of intermodality (speedy trains to reach hubs)?

10. Crossing impacts with stakeholder feedback:
Example with infrastructures:
Stakeholder feedback:
In the experts’ opinion, as compared to the technological and organisational components, it is the infrastructures needed for Goal 1 that will take the longest time to be ready. This could be construed as an indication for the European ATS to invest in this domain most urgently so as to reach the stated objective.
Generally on infrastructures, unanimous support for the development of inter-modality, connecting small airports to land or water-based transportation
First area of interest for a recommendation:
do we have the possibility to assess the impact of more direct flights on existing infrastructure capacities?
are we able to compare the benefits of more direct flights with the benefits of approaches including more intermodality?

11. Crossing areas of interest with the work of other WPs:
Example with assessment of FP6/FP7 projects:
Impact of more direct flights on existing infrastructure capacities
Not much addressed in projects
Many projects insist on increasing airport capacity but are rather focus on larger airports / hubs
How hub congestion would or would not be relieved by a more distributed model seems not addressed
Comparison more direct flights / more intermodality
Projects addressing intermodality generally focus on journey planning (e.g. enhanced wisetrip) based on existing means, thus not providing a simulation framework where various scenarios could be tested
These projects however suggest that adaptation to disruptions should be taken into account in the assessment

20. Results – Infrastructures 1
Q211
Would you say that building new regional airports all across Europe is…?
• Essential/urgent: there are not nearly enough regional airport platforms throughout Europe.
• Desirable: the transport connectivity needed can be improved by developing the land transport links as well.
• Indifferent: the existing airport platforms in Europe are sufficient.

21. Results – Infrastructures 2
Q211 – open question
Apart from their number and locations, what do you think are essential airport infrastructures missing in Europe to improve TE (e.g. non-conventional platforms for seaplanes or V/STOL aircraft)?
A few: “Dedicated or adapted airports for EPATS/P-planes, seaplanes, V/STOL.”
Many comments: “The flight time per se is not the most TE-costly part; airports should accelerate security checks, airplane access, boarding-disembarking.”; ”New airports’ locations should be carefully planned wrt. (densified) ground transport network.”
A few: “Need to reduce the environmental impact of air travel.”

22. Results – Infrastructures 3
Q212
Would you say that the European airport-to-airport and airport-to-city land transport network shall be…?
• Developed and improved, especially the rail segment.
• Developed and improved, especially the road segment.
• Left as it is, just modernise the vehicles and increase the connection frequencies

23. Results – Technology 1
Q221
Would you say that today’s European ATS’ weather forecast/now-cast systems…?
• Cannot meaningfully be improved on their own, better use of their data suffices.
• Can and should be improved in terms of accuracy.
• Can and should be improved in terms of frequency.
• Can and should be improved in terms of resolution.

24. Results – Technology2 Would you say that ATC automation…?
Q222
Would you say that ATC automation…?
• Must be implemented mainly on ground systems (automated trajectory design).
• Must be implemented mainly on-board (automated datalink-transmitted orders execution).
• Must include both the ground and board systems.
• Should progress, in the long term, toward pilot-less aircraft.
• Should progress, in the long term, toward fully automated ATC.
• Is not needed in order to reach ACARE’s TE objectives.

26. Main conclusions

27. Conclusion and perspectives
Need for quantitative impact assessment, i.e. simulation means / models for:
Passenger flows in airports
Various aspects of intermodality
As evidenced in the tech watch, only partial models exist for intermodality but the issue starts to be addressed for passenger flows
Per domain:
Technology: not a major limiting factor, strong case for automation
Organisation: very qualitative answers, need for quantitative measures
Infrastructure: a strong impact of policy, infrastructural investment, and governance is identified
